Star Like Object..mimics the north star..and shoots out into atmosphere.

We were just about to depart for a night of boating on the Intercoastal,.When we noticed an object that appeared to be the same shape as a bright star..as we were watching it made a half moon movement around the star. Almost rotating around the star..then.its glow got smaller..it shot out into space with incredable speed. we could still see it barely..as it headed north. but by this time, it was well above any distance in which a any commercail airline would fly.As it proceeded out into the atmosphere, we could see a trail coming from the back of the object.This was the second sighting by myself.and the first for the others that were with me.
